I know this topic has been discussed and the damage caused by the ethanol in gas is well documented. While gassing the boat I had a conversation with a guy who just spent 3K repairing his boat from ethanol damage. We all put that preservative in our tanks for the off season but his mechanic told him unless you are using your boat every week then you need to put that preservative in to protect your fuel lines from getting corroded by the ethanol.

Was curious what everyone's thoughts are on this area. I am typically 3 weeks maybe between outings. Is that enough time for the ethanol in the gas to cause damage? I am thinking that as the years pass it might be so would it be better to put some stabilizer in after every trip out on the water for preventative reasons?

I am running E85 and I put a little Marvel Mystery Oil in the tank to help keep every thing lubed and looking good. Third year with no damage, I drain the carbs every winter and spray them with WD40.

havent had any issues with fuel lines and boat does sit for a while at times.

Although last year i did have to replace a mechanical fuel pump the diafram was cracked away.boat is also a 93 and may have been the second fuel pump on it too??

I also run E-85 and use marvel mystery oil when i store the boat in the winter.You need to add it then start motor up to circulate it thru out fuel system.

There is no documentation of fuel lines being damaged by ethanol, only hysterical claims. Ethanol is compatible with more types of rubber, plastic, and metal than gasoline and aromatics. Long before ethanol could cause damage the gasoline and aromatics would have already caused it.
